JOINT FOR BRACELETS.

To all whom it may concern:

Be it known that we, CHARLES BILLINGTON and RALPH FENNO GriBBs, citizens of the United States, and both residing at Attlehero, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Joints for Bracelets, of which the following is a specification.

Our invention consists in a two-part joint for bracelets, having the parts so arranged and interlocked as to permit the bracelet to be opened for a certain distance to allow it to be passed over the hand of the wearer, and closed on the arm.

The object of our invention is to produce a cheaply made movable joint, without the employment of pivot pins and the like, which by wear are apt to drop out and be lost.

Figure 1 is an elevation of a bracelet, with the lower part in section to show the joint. Fig. 2 is a perspective view of the top of the joint with the joint closed. Fig. 3 is a top view of the joint with the joint open. Fig. 4 is a longitudinal section on line IV- IV of Fig. 6. Fig. 5 is a longitudinal section on line VV of Fig. 3. Fig. 6 is a bottom view of the joint with the joint closed. Fig. 7 is a transverse section on the line VII-VII of Fig. 5.

The joint is formed of two members A and B. These members each consist of two parts, c'. 6., the parts CG through which the members are attached, by soldering or otherwise, to the interior of the bracelet D, and the parts EE which are interlocked to form a movable sliding joint. The part E has formed in it a slot F adapted to receive an ear G on the end of the part E which ear when the bracelet is opened, coacts with the end wall H of slot F to limit the movement of members A and B of the jointrelative to each other.

The part E is provided with ears I which are turned over the part E and which serve to hold the parts E and E in operative rela- Specification of Letters Patent.

tion. The part E has alsov formed in it a slot J in which is located a correspondingly shaped elevation K on part E The parts CC are shown convex on one side and concave on the other in the direction of their length, and the parts EE convex on one side and concave on the other in the transverse direction of the joint.

We wish it understood that we do not limit ourselves to the particular shape of the members of the joint, as modifications will be obvious to those skilled in the art.

Having thus described our invention, we claim:

1. In a bracelet hinge, duplicate body portions each provided with a curved interlocking portion, one of said interlocking portions being provided with a longitudinal slot and a groove adjacent said slot, a rib on the other portion adapted to enter said groove, an ear on said portion located within said slot, and laterally dis osed ears on the first mentioned interloc ing portion adapted to be bent to hold the two portions in engagement.

2. In a bracelet hinge, an attaching member, a curved member extending therefrom, said member being provided with a longitudinal slot and a groove, laterally extending ears carried by said member and adapted to be bent into clamping position, a complemental attaching member, a curved member extending therefrom and slidably engaged between the aforesaid curved member and the ears, an car on said last mentioned member adapted to enter the slot, and a longitudinal rib on said curved member adapted to enter the groove.

In testimony whereof, we aflix our signatures, in the presence of two witnesses.
